All our hash functions are based on siphash24(), factor out
siphash_init() and siphash24_finalize() and pass the siphash
state to the hash functions rather than the hash key.
This simplifies the hash functions, and in particular makes
composition simpler as calling siphash24_compress() repeatedly
on separate chunks of input has the same effect as first
concatenating the input and then calling siphash23_compress()
on the result.

This is specifically useful for appending the mDNS ".local" suffix to a
single-label hostname in the most correct way. (used in later commit)

Given three DNS names this function indicates if the second argument lies
strictly between the first and the third according to the canonical DNS
name order. Note that the order is circular, so the last name is
considered to be before the first.

Intended to be called repeatedly, and returns then successive unescaped labels
from the most to the least significant (left to right).
This is slightly inefficient as it scans the string three times (two would be
sufficient): once to find the end of the string, once to find the beginning
of each label and lastly once to do the actual unescaping. The latter two
could be done in one go, but that seemed unnecessarily convoluted.
